• FiL : filter parameter programming
menu.
This function allows you to stabilize the
instruments digital display, in order to
obtain steady readings and better con-
trol.
Fi.S
: filter working range. The coeffi-
cient is given in digits and defines the
range in which the filter works, pro-
grammable value: 0 < Fi.S < 9999
The programmable numerical value
represents the fluctuation range of the
value which has been measured and
displayed by the instrument. In the first
configuration phase this value must be
0 and the right value is to be entered
only after the verification of the possi-
ble fluctuation.
Example: if the measured instantane-
ous value varies from 10.00 to 10.06,
the "Fi.S" value to be entered is 0.06
(10.06 - 10.00).
Fi.C
: filtering coefficient value. Pro-
grammable value: 1 < Fi.C < 255.
The higher "Fi.C", the higher the filter-
ing of the measured value and the
longer the updating time of the dis-
Example: minimum measured value = 100, that must correspond to a
retransmitted signal of 4mA.
"Lo.A" (%) = 100 * ?mA that in our example corresponds to:
20
played value, the control set-points and
the analogue output.
NOTE: for a correct working of the
filter, the relative coefficient must sat-
isfy the following relationship: 1 < Fi.C
< (Fi.S x 8) < 255.
• A.ou : analogue output programming
menu.
Lo.A
: value to be expressed as % of
the output range (0/20mA-0/10V) to be
generated in correspondence with the
minimum measured value. Value pro-
grammable within the range: 0.00 < Lo
< 99.99.
Hi.A
: value expressed as % of the
output range (0/20mA-0/10V) to be gen-
erated in correspondence with the
maximum measured value (Hi.E/Hi pa-
rameters). Value to be programmed within
the range: 0.00 < Hi.A < 99.99.
